These Giro Disc 2-piece rear rotors are a direct replacement for the factory rear discs, taking mass off the rear axle while the floating iron rings handle repeated hard stops better than the one-piece stock disc.\u003c\/p\u003e\u003ch3\u003eHow GiroDisc builds it\u003c\/h3\u003e\u003cp\u003eEach assembly is fully floating: a slotted iron ring rides on drive pins around a separate aluminum hat. The ring is machined from a proprietary high-carbon iron casting made to GiroDisc's own specification, which holds up better under hard use. Its 48 curved vanes act as a centrifugal pump, pulling air in through the hub to cool the rotor. GiroDisc makes the hats, rings and drive pins in-house in Bellingham, Washington, from domestically sourced material. The hat is 6061-T6 aluminum with a black anodized finish, and the high-strength alloy steel drive pins are cadmium plated against corrosion. Spring clips and Belleville washers give the ring race-ready float without rattling from loose hardware on the street.\u003c\/p\u003e\u003ch3\u003eReusable hats\u003c\/h3\u003e\u003cp\u003eBecause the hat is a separate part, you only replace the iron when it wears out. New GiroDisc rings (D2-187) bolt onto the hats you already have, which costs much less over time than buying complete rotors. Replace the rings at 20 mm minimum thickness, or sooner if a crack reaches the outer edge of the ring.\u003c\/p\u003e\u003ch3\u003eWhy 352 mm and not 356 mm?\u003c\/h3\u003e\u003cp\u003eAudi lists the factory rear rotor at 356 mm, but that number is misleading. The flower-shaped factory disc only reaches 356 mm at the outer tips of its petals. The pad actually sits about 2 mm inside that edge, so GiroDisc sized its round ring at 352 mm to match where the pad contacts the rotor. You lose no swept area.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eTwo assembled rear rotors, one per side, each iron ring already mounted to its aluminum hat.
